It’s surprising how simple the design of a solar bottle light is – take an empty plastic bottle, fill it with mineral water and a few drops of bleach, and cement it halfway through a small metal roof sheet (the kind used as roofs in Manila’s slum areas). Then cut out a small piece of the actual roof, place the sheet with the bottle on top of the hole, cement any cracks, and voilà! Let there be light.

This initiative, a project designed and developed by students from the Massachusetts Institute of Technology (MIT) and implemented by MyShelter Foundation, is already transforming lives of low-income people in the Philippines.
